Has it ever bothered you that so much configuration of blocks, items, recipes,
\nand now even enchantments is defined in untyped JSON files? Well then you should
\nprobably just use
\ndata generation which
\nis much more battle tested and even used by Mojang for the Vanilla data. _But_,
\nif you _also_ want to be able to adjust the data dynamically or want some things
\nto be configurable, then this might just be the thing for you. YARRP is inspired
\nby ARRP and
\nBRRP but written from the ground up with an
\neasy to use Kotlin API. It allows you to create resource packs (i.e. both data
\npacks and asset packs) at runtime, so you don’t need to have JSON files ready
\nfor all possible options.<\/p>\n
## Usage<\/p>\n
To add YARRP as a dependency, add the following to your `build.gradle.kts`:<\/p>\n
“`kotlin
\nrepositories {
\n \/\/ you can use either one
\n maven(“https:\/\/jitpack.io”)
\n maven(“https:\/\/api.modrinth.com\/maven”)
\n}<\/p>\n
dependencies {
\n \/\/ replace the versions and loader as needed. the loader is one of `fabric` or `neoforge`
\n modImplementation(“com.github.RubixDev.YARRP:yarrp-mc1.21.1-fabric:v0.2.0”) \/\/ when using jitpack
\n modImplementation(“maven.modrinth:yarrp:0.2.0+1.21.1-fabric”) \/\/ when using modrinth maven
\n}
\n“`<\/p>\n
Don’t forget to also list YARRP as a dependency in your `fabric.mod.json` and
\n`neoforge.mods.toml` files.<\/p>\n
You can then use YARRP by creating a pack and adding it to one of the register
\ncallbacks. Here’s an example:<\/p>\n
“`kotlin
\nobject MyModResources {
\n \/\/ call this in your mod initializer
\n fun register() {
\n YarrpCallbacks.register(PackPosition.AFTER_VANILLA, ResourceType.SERVER_DATA) {
\n add(PACK)
\n }
\n }<\/p>\n
@JvmField
\n val PACK = RuntimeResourcePack(
\n RuntimeResourcePack.createInfo(
\n Identifier.of(“modid”, “my_runtime_pack”),
\n Text.of(“Pack Title”),
\n “pack version”, \/\/ should probably be set to the version of your mod
\n ),
\n RuntimeResourcePack.createMetadata(Text.of(“pack description”)),
\n )<\/p>\n
